UNITED STATES FRANK H. STAl-IL, OF OHARLESTOWN WEST VIRGINIA, ASSIGNOR TO THE POWHATAN BRASS AND IRON WORKS, OF SAME PLACE.

SELF-CLOSING C OCK OR FAUCET.

SPECIFICATION forming part of Letters Patent No. 661,003, daL-ci October 30, 1900.

Application filed April 18,1899.

To all whom it may concern/ Be it known that I, FRANK HENRY STAHL,

.a citizen of the United States, residing at Charlestown, in the county of Jefferson and State of West Virginia, have invented certain new and useful Improvements in Self- Closing Cocks or Faucets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as IO will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to self-closing cocks or faucets; and the primary object of the invention is to provide a cock or faucet of this nature with a valve having its valve-disk seat itself on the pressure side of the diaphragm, whereby to be acted upon by the water-pressure to close the valve-port in said diaphragm. A further object is the construction of the cock or faucet in sucha manneras to readily permit the application and removal of the valve-disk and its operating parts through that part of the cook or faucet in which is located the valve-stem.

To these ends the invention consists in providing the valve-port of the diaphragm with a removable valve-seat, which is designed to be applied through the valvestem chamber as a bushing to said valve-port and after the valve-disk has been passed therethrough to the pressure side of said diaphragm, thus permitting the application and the removal of the valve-disk through the opening in the valve-stem chamber.

The invention further consists in certain novel features in the construction and arrangement of parts, all as hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a view and side elevation of the improved cook or faucet; Fig. 2, a transverse vertical sectional view taken through Fig. 1. Fig. 3 is a detailed view showing a front elevation of the handle-supporting part of the faucet, 5 the same being shownwith the inclosing cap removed therefrom; Fig. 4, a detailed View showing the valve-stem and valve-disk in side elevation, and Fig. 5 a horizontal sectional view taken through Fig. 4-on the line so 00.

Referring to the drawings, 1 indicates a Serial No. 713,453. (No model.)

the main casting of which comprises the usual screw-threaded inlet or pipe-section 2 for connection with the water-main, a spout 3, and

a valve-stem chamber 4. The valve-stem chamber is interiorly SCI'G w-threaded, as at 5, and receives the screw-threaded portion 6, in which is supported the depression-pin 7-and the handle 8 for operating the pin, which said portion 6 serves as the means for closing the opening to the valve-stein chamber, readily allowing the removal or insertion of the valve and its operating parts without the necessity of disconnecting the several parts assembled in said portion 6, the specific construction of which and its cooperating parts will hereinafter fully appear.

The diaphragm 9 is provided with an opening of sufficient size to permit the passage therethrongh of the valve disk 10 and is screw-threaded to receive a valve-seat 11, exteriorly screw-threaded, which is carried by the valve-stem 12 and turned through the agency of said stem to screw it into the diaphragm-opening and bring the flange 13 to bear on the upper surface of the diaphragm, which is preferably reduced for the purpose of effecting the perfect seating of said flange.

The opening through the valve-seat 11 is preferably of angular form to receive in the corners thereof the ribs or projections of the valve-stem,so as to cause both stem and valveseat to be turned together, while permitting the necessary reciprocating movement of the stem therein. The stem is preferably hollowed out between the ribs to form spaces 14 between the stem and the seat for the passage of the water when the valve-disk is pushed down.

The upper end of the valve-stem is pro- 0 vided with a pin 15, inserted in a transverse opening therein, which pin not only forms the means for turning the stem in applying or removing the valve-seat 10, but secures inplace a washer 16, which receives the tension of the 5 spiral spring 17, normally held under tension between the said valve-seatand the washer, the effect of which spring is to assist the valve in closing. It should be understood that the present invention does not depend on the spring 17 for its self-closing action, as the faucet, which may be of any suitable form,

placing of the valve-disk on the pressure side of the diaphragm insures this result, and without the necessity for the spring, which can be dispensed with without materially affecting the self-closing action, but which is retained merely to initially actuate the valve that the' water-pressure may the more readily act upon the valve-disk.

The depression-pin 7 is normally supported on the end of the valve-stem and would, if the valve-stem were removed, drop to the position assumed by it in Fig. 3, in which its cross-bar or head 18 rests on the floor of the recess 19, in which it has its reciprocation in the supporting part 6. The connecting end of this part 6 is cored out to form a recess 20 for packing material and is screw-threaded to receive a screw-threaded packing-plate 21.

The handle 8 for operating the faucets valve may be of any desired form and has its shaft 22 mounted in slots 23, formed in the side walls of recess 19 and in the direction of the said recess and the cross-bar 18 of the pin. These mounting-slots 23 permit the ready application of the shaft 22, which is provided with a depression part 24, having an under and engaging face 25, against which the head or cross-bar of the pin is held by the valve-stem and upon which cross-bar the said face 24 has a depressing action as the shaft is turned in either direction. This depressing action is accomplished by virtue of the travel downward of one or the other of the outer edges of this engaging portion, which are practically the ends of a lever whose ful-' crum is the axis of a shaft which is horizontally intersected by the said engaging face, thus forming of this engaging portion two short depressing-arms. Preferably the depression part 24 is in cylindrical form and of a size larger than the trunnion part of the shaft and is recessed to provide the bearingface 25 for the head or cross-bar of the depression-pin. Depending sides 26 are thus provided to form a guide for the head or crossbar and retain the same in engagement with the bearing-face 25. A cap 27, having vertical slots 28, is fitted snugly over the supporting part 6, thus inclosing the same and holding the shaft of the handle securely in slots 23. I

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent A cock or faucet having the Waterway-opening of its diaphragm provided with a removable valve-seat, a valve-disk located so as to bear on the water-pressure side of said seat and insertible through said water-way opening when said seat is removed, and a valvestem adapted to reciprocate through said valve-seat and be rotated to rotate the same, substantially as described and for the purpose set forth.

In testimony whereof I have affixed my sig nature in presence of two witnesses.

FRANK H. STAI-IL.
